Description

SUBSTANCE: invention relates to medicine and can be used during video laparoscopic operations, staged videoscopic sanitation of the omental sac for evacuation of pathological effusion, blood, clots and washing of the abdominal cavity.

Known irrigator-aspirator (aquapurator) for the sanitation of purulent cavities, which consists of a hollow thin-walled metal tube with a cut at the end and having on the distal working part 4 additional holes on the walls for spraying liquid, and on the proximal part - valves for regulating the inflow and outflow of liquid . The irrigator-aspirator is connected by hoses to a pump that pumps liquid and a container for collecting outflowing sanitation products (operating manual WIS AP Aqua-Purator 1610).

The disadvantage of this device is low efficiency in some cases, especially in the presence of a cavity of complex shape, thick contents in it or areas of purulent-necrotic tissues fixed to the walls of the cavity.

A device for endoscopic hydropressive processing, irrigation and aspiration is known, in which an additional tube is attached along the main tube. On the proximal part of the additional tube there is a valve mechanism that regulates the flow of fluid, connected by a hose to a pump of 4-5 atm. The distal part of the additional tube is bent in such a way that the bending elbow is located at the level of the distal cut of the main tube. The distal parts of both tubes are inside the nozzle, which is a cylinder 16-20 mm in diameter, 3-4 cm high with two circular grooves 6-7 mm wide, up to 3 mm deep, dividing the cylinder into three equal parts. At the distal end of the cylinder there is a spherical recess with a hole at the bottom. On the proximal chamfer there are four holes opposite each other. (RF patent for the invention RU 2294766 C2, published on March 10, 2007).

But this device is multicomponent and difficult to use.

The closest in technical essence is a device for washing and drying the abdominal cavity during laparoscopic operations, which contains two coaxially arranged tubes, the outer one is equipped with a handle, and the inner one is equipped with a thrust ring, having the possibility of axial movement, during which the distribution mechanism is switched, consisting of nozzles for receiving and liquid supply on the outer tube, and slots on the inner tube, when moving which alternately switches the suction or liquid supply modes, and at the working end a corresponding change in the configuration of the instrument occurs, allowing the device to operate in double-lumen or single-lumen suction modes or be used for washing. A locking mechanism is introduced into it, including a springy plate, fixed in the grooves, to hold the tubes in a given relative position (RF Patent for the invention RU 2222352 C2, published on January 27, 2004).

However, the device is technically complex and time-consuming to manufacture and use.

The result of the proposed technical solution is the possibility of using it in the process of sanitation of the abdominal cavity, closed cavities of complex shape, in the presence of clots and purulent-necrotic masses.

The figure 1 shows the nozzle on the aquapurator, where: 1 - a tube with a diameter of 10 mm; 2 - funnel-shaped stop in the proximal part of the tube; 3 - auger; 4 - disc-shaped handle for screw rotation; 5 - standard 5 mm tip for aquapurator.

The tip on the aquapurator 5 serves as a guide and axis for the screw 3, which is coaxially connected to the tube 1.

The technical action of the nozzle on the aquapurator is carried out by rotating the disk-shaped handle 4. In this case, the screw 3 rotates, which fragments, captures and moves dense fractions (clots, necrotic tissues) through the tube 1.
